FEATURES and BENEFITS

1. Extended service life and low maintenance costs due to unique helix coil stem design, which enables friction-free opening and closing

2. Improved product quality, efficiency and safety with tightness performance up to ANSI FCI-70-2 Class VI

3. Easy in-line inspection and maintenance enabled by top-entry design

4. Reduced corrosion due to heavy wall thickness in excess to ASME/ANSI B16.34

5. Improved personnel safety from blowout-proof stem that meets international standards of API 600 and 6D

Other Features

1. Combination of a quarter-turn ball valve with a linear movement of non-rotating stem

Trunnion mounted design

2. Reduced or full bore

3. Single seat (no valve body cavity)

4. Unidirectional or bidirectional

5. Metal to metal seat with stellite welding overlay (soft seat insert on request)

6. Outside screw and yoke for adjusting of stem packing

7. Blowout proof stem

8. Suitable for very high frequent cycling operations (switching valves)

9. Tight shut-off by means of application of external mechanical force and not dependent on differential pressure

10. Proper selection of materials to avoid galling and high friction

11. Protected lower trunnion against solid particles intrusion

12. Clearance control to consider high/low temperature shrinkages

13. Self-cleaning closure member
